Novel Dy 3+ and Ce 3+ doped Si – B – Na – Sr ( SBNS ) glasses were synthesized by melt‐quenching technique. Excited by 327 nm, the 0.5Dy 3+ ‐and 0.5Ce 3+ ‐doped SBNS exhibits white emission with Commission Internationale de L'Eclairage coordinates of (0.308, 0.280). Basic optical characterizations have been performed by measuring the absorption and emission spectra and calculating Judd–Ofelt intensity parameters, radiative probability, luminescence branching ratio, cross sections, and effective bandwidth. The Judd–Ofelt parameters Ω 2 , Ω 4 , and Ω 6 indicate a high asymmetrical environment and covalent environment in the optical glass. The emission color of Ce 3+ and Dy 3+ codoped transparent glass can be tuned from blue to white through energy transfer from Ce 3+ to Dy 3+ ions. The resulting glass may have potential application in white‐light‐emitting source.
